Specification of Letters Patent.

Fig. l2 is a: side elevationof a portion ofl the mechanism illustrated iii-Fig. 11;, and

Fig. 13 is an enlarged elevation ofthe pawl .and ratchet -mechanism employed for the purpose of automatically advancingy the carriage.

Referring now to the drawings wherein is Y illustrated the preferred forni of my invention4 the numeral ll designates substantially U-shaped supports between thejextreniities of whiclia pair of duplicate rack bar sQare clamped, the clamping operationfbeing effected Vthrough the medium of thumb screws; 3 carried by the supports .1. and engaging extensions -l of the said rackbars, the latter Abeing designated as an entirety by the said y numeral v2. A headportion is formedinfl vtegi'ally with-each rack bar, vthe said. head portion being disposed to extendat anangle tothe dependinglportion 4' andto engage a connection with the present invention.

The carriage is divided:longitudinally as is illustrated to. advantage in Figs.Y 6 and 7 longitudinal groove 6 ,formed within the base portion/7 of the carriage employed in of the drawings andhas securedatfeacli end thereof clamping blocks 8,each of whichis provided with an. extension 1 9 A .having g gage nating in arecessed extremity within which the saidl pointed extremity is Vseated',this. arrangement providing for minute -adjustment of the sections'of which the carriage is composed'. Lateral adjustment `of the said knob 12,.the manipulation ofY which will move the said carriage sections toward. or

away fromeach other as occasion demands. Adjacent one end of the carriage, and upon each carriage section, I. provide an upright 13l terminatingin a bifurcated Aextremity 14 within which detachable bearings 15 are seated, the latter being maintained immovable during the operation ofthe de.

thereto, at one end thereof, a sprocket wheel.`

18, thus providing, ina manner to behereinafter fully described, for the rotation of lOO lllO

the said shaft. Comparatively large eccentrics 19 are secured to theshaft 17, one eccentric being disposed adjacent each bear-l Smaller eccentr1cs20 are secured ing 15. v j to the said shaft, the said smaller eccentrics being either integral with or independent of the larger eccentrics 19. A ring or band 21 is arranged over the periphery of the smaller eccentrics 20, the said ring having pivotally secured thereto as at 22 at diametrically opposite points links 23, the opposite extremities of which are pivoted` as at 24 to sleeves 25 one of which is mounted for sliding engagement upon a screw rod 26 extending transversely of the links 23. An expansion spring 27 is arranged to embrace the rod 26 between the sleeves 25, the

ends of the said spring abutting the said sleeves to normally exert outward pressure thereupon. A thumb nut 28 is threaded upon the rod 26 to provide for adjustment I vof the sleeves, the purpose of the adjustment being apparent upon further reading of the specification. Pivoted as at 29 to each sleeve 25 is a link 30, each link terminating at a point 31 where it is in turnv forengagement with vertical grooves 34" formed within suitable guides 35 1n turn formed integrally with or secured to the inner face of one of the uprights 13.

A lip 36 is formed upon each block 32 at its'lower extremity, the said lip being disposed for engagement with a bell crank 37 pivoted as at 3S between lugs 39 formed integrally with or secured to adjustable blocks 40. To normally maintain the said lever 37 in Aengagement with the lip 36, a coiled spring 41 has been provided, one end of the spring being disposed for engagement with the said lever and the opposite end for engagement with the said block 40, the spring intermediate its ends, being coiled about the pin upon which the lever 37 is pivoted. An opening 42 is formed Within the block 40 between the lugs 39 through which the opposite end of the lever 37 from that engaging the lip 36 depends, the said opposite end being seated within a cut-out 43 formed within a reciprocating anvil block 44, theV latter being` supported lupon the base portion 7 of the carriage andwlthin a groove 45 formed within the block 40. The inner the anvils 44 are reciprocated simultaneously and that the teeth of the saw, disposed in the path thereof, are alternately bent or set in the desired manner.

Each anvil supporting block 40 is adjustable, such adjustment being eected through the medium of a lever 47, one end of whichr a knob 52 carried by the lever 47 may be seated, the said notches being positioned in the are of a circle described from the longitudinal axis of the shaft 48. To limit the sliding movement of the blocks 40, lugs 53 are provided, the said lugs being disposed in the path of the blocks 40 and for engagement with recesses or cut out portions 54 formed therein. lIf desired, the lugs of the Y respective blocks maybe connected by means` Y- of a bridge plate 55, the latter serving in Y the capacity of a guide for the said blocks 40 during their sliding movement. n

Upon each side ofthe carriage, I provide a lateral extension 56 adjacent which is pivoted as at 57 'an operating lever 58 the free endv ofV which is normally maintained in spaced relation to the extension 56 by means of a spring 59 interposed'therebetween. The

inner end of the lever is pivoted as at'f60 to movable securing blocks 61, the adjacent edges of which are normally disposed to extend 'parallel' asfis illustratedv to advantage angle as indicated at62 whereby movement of the said blocks in one direction is limited.

To operate the blocks, during the arrangement of a saw therebetween, the levers 58 are forced toward the extensions 56 'of the i carriage causing the said blocks to move, one away from the other. After arranging the saw therebetween, the levers 5S are released thus permitting the springs 59 to returnthe said blocks to their normal position where upon the adjacent edges will engage lightly the opposite faces of the saw. The blocks l6l only engage the saw to such an extent as `to obviate the bending movement of the saw when acted upon by the sharpening element and of course permit the said saw to move" longitudinally between the blocks.

Passing on to the description of the mechanism employed for imparting movement to the carriage, 63 designates a suitable shaft having a ratchet wheel 64 mounted upon one end thereof, the teeth of the said ratchet being engaged between a ypivoted spring pressed pawl carried by amovable bracket 66 loosely mounted upon the said shaft 63. An extension 67 is formed integrally with the bracket 66, to the extremity of which an arm 68 is secured as at 69. The arm extends forwardly and terminates in a right angled extension 70 between which and a similar extension 71V also carried by the said arm, a spring' 72 is interposed, the said spring being arranged to embrace a rod 73 slidable with respect to the extensions 70 and 71,4the said rod being lsecured as at 74 to an ear 75 formed integrally with an adjustable bracket 76 movable vertically upon a rocker frame designated as an entirety by the numeral 77, the said frame being pivoted, the shafts 48 above mentioned serving as pivots therefor.

Vertical adjustment of the bracket 76 is ef fected through the medium of a screw rod 78 operable by means of a thumb nut 79 mounted upon one end thereof. A yoke 80 connects the two vertical sections kof which the frame 77 is composed. One of the sections, the one to which the rod 73 is secured, has secured thereto in any suitable manner,

an arm 81 the opposite end of which is pro-` vided with an elongated opening 82 within which a `pin 83 works, the latter being sup ported by means of a link 84 arranged to embrace a suitable shaft 85, square in cross section, and journaled within bearings 86 provided therefor. A spring 87, one end of which is secured to the pin 83, and the opposite end to a pin 88 projects from the said arm 81 -and is provided to normally maintain the said pin in engagement with one end of the slot.

As a means for imparting movement to the rocker frame 77, I provide arms 89 one end of which is secured as at 90 to eXtensions 91 formed one upon each of the rocker frame sect-ions` the opposite ends terminating in bands 92 arranged to embrace or engage the periphery of the large eccentrics 19 mounted upon the shaft 17 above referred to. From the above arrangement it is apparent that by the rotation of the shaft 17, the frame `7 7 is rocked upon its pivot formed by the shafts L18.

The lopposite section of the rocker frame 77 from that having the rod 73 secured thereto is in substance, a duplicate of the section above described, the same comprising a screw rod 93, bracket 94 and thumb nut 95. Secured as at 96 to the bracket 94 is an arm 97 the opposite end of which is pivoted as at 98 to a cam 99 mounted upon the shaft 85 at its opposite end from that engaged by the link 81. A pin '100 projects inwardly from the cam 99, the purpose of the pin being hereinafter fully described.

Upon the shaft 63 and rotatable there-- with I provide a pair of serrated blocks101,

the serrations being arranged in series, the;

said series being so4 arranged as to provide for the gaging of the carriage movement according tothe pitch fof thesaW acted upon. A pawl 102 is-movable `with the shaft the said pawl being slidable throughout the length of the said shaft, its freev end engaging the serrations` of the blocks 101 to limit rotation of the said blocks according to the adjustment of the said pawl.v Graduation markss108 may be provided upon the shaft 85 to facilitate proper adjustment of the saidnpawl. Be-V tween the blocks 101 of the shaft163 and disposed for engagement with the-rackbars 2 I pr-ovide a pair of uniformly spaced gear wheels 104, one wheel being disposed for engagement with each rack bar 2, such en' gagement providing for thesliding Inovement of the entire carriage according to the rotation of the shaft 63 upon which the said wheels 101 are mounted. vAt the opposite end of the carriagefrom that upon which the uprights 13 are formed, uprights 105 are provided, one upright at each side of the carriage. Each upright4 terminates in a bifurcated end 106 vto'pro! vide for a removable mounting of bearings` 107, the latter having a shaft 108 journaled therein. Set screws 109 are adapted to maintain the said bearings 107 in the bifurcations provided therefor.r Upon one end of the shaft 108 is mounted a pulley 110', through the medium of which, motion is transmitted from any suitable source of power to the entire machine, the opposite end of the shaft 108 having mounted` thereupon a hand operatedwheel 111 to provide for the manual operation of the'machine if so desired. Between the bearings 107, the shaft 108 serving as a pivotal support, I provide an oscillatable frame 112terminat'- ing at its free end in a head portion v113 having graduation marks 114 formed thereupon. Extending transversely of the head 113 is a removable spindle 115 terminating at its lower extremity in a disk like base 116 hav-ing a recessed lower face 117. Thebase f 116 is enlargedv as at 118, the said enlarge-y ment serving as a bearing for a shaft4119 upon one end of whicha circular file 120 is mounted, a thumb screw 121 being provided to maintain the said file upon the said shaft. A bracket 122 is formed integrally with ther enlargement 118 to provide, an'additional bearing for the shaft 1.19.`4 Between, the bracket andthe enlargement and mounted uponthe said shaft 119 is a beveled gear 123 adapted forengagement with a like gear 124 mounted for rotation upon the spindle Y115k and having a recess 125 formed .therein within whichithe base 116 of the saidv spindleis seated.` Bearing-balls 126 are pro` vided, ,wherever necessary, to facilitate the., rotation of the Aseveral gears. The said,i gear 124E is also disposed for engagement witha' beveledpinion 127 mounted upon la shaft 128 ournaled within bearings formed by the head 113 and an enlargement 129 of the frame 112. A second pinion 130 is mounted upon the shaft 128 adapted for engagement with abeveled gear 131 mounted Y upon the shaft 108, this engagement transmittingV therotary movement of the said shaft 108'to the'several gears and pinions above `referred to and finally to the circular tile 120. The spindle 115 is angular in cross section at one end and has arranged thereover a plate member 132 whereby movement may be imparted to the said spindle to pr-ovide for the angular adjustment of the file 120. To ascertain the desired adjustment a lip 133 is formed integrally with the plate 132, the said lip being disposed for engagement with the yhead 113 and particularly the graduated or notched portion 114 thereof. A thumb nut 134: is provided to support the spindle in the proper position necessary to operation. p

Secured to the frame 112 at one side thereof and depending therefrom I provide a specially formed plate member 135 having a notch 136 formed therein at a point adjacent its lower extremity. The pin 100 above referred to is adapted for engagement with the saidv plate 135 and the notch 136 to oscillate the frame 112 and the mechanism carried thereby during a rocking of the frame 77. A sprocket 137 is mounted upon the shaft 108 over which a suitable sprocket chain 138 is arranged, the said chain being also disposed for engagement with the sprocket 18 to transmit motion to the shaft 17 necessary to theoperation of the machine.

The structure of the vmachine having been described in detail, it now remains to set forth the operation thereof. The band sawy acted upon, the teeth having already been cut, is first clamped between the rack bars 2 by manipulating the thumb screws 3, the toothed edge of the saw being disposed upon a plane slightly above the teeth of the rack bars 2 in the path of the anvils 114. The carriage is then set so that the said anvils will engage, during operation, the teeth at one ,to the frame 77 as well as a reciprocatory movement imparted to the blocks Movement of the blocks 32 will actuate the bell cranks 37 and reciprocate the anvils 44, causing the latter to engage the teeth of the sa-w and bend or set the same in the desired fmanner, this being accomplished 'by reason of the engagement between the-beveled extremities 416 of the anvils and the said saw teeth. The anvil carrying blocks 40 may be adjusted so as to act upon saws varying in pitchythis being effected by `manilmlation of4 the-lever 17 as it is apparent Vupon referencefto Figs. 8' and 9 ofthe drawings that the said blocks 40 may be moved by reason of the engagement of the pawl -50 therewith. The lugs 53limit the movement of the said blocks. The length of the reciprocatory stroke ofthe blocks 32 maybe varied by adjusting the thumb nut28 upon the rod 26, for instance, when it is desired that the stroke should be lengthened, the said thumb nut 28 isrotated so as to Vcompress the spring 27 andinove the sleeves-25 into closer proximity 'and thereby increase the Vdistance between the pivotl point 31 andthe eccentric 20. To shorten the length offthestroke, a reverse operation of the thumb nut should be effected.

The rocker frame 77 being pivoted as at 418 and connected tov thev shaft 17 through the niediumofthe eccentrics 19 and arms 89, it is apparent that oscillatory movement is imparted to the said frame during the rotation of thc shaft. The frame, at one side, is connected to the shaft 63 by means of the rod 73, arm 68 and bracket 66, the latter havingv a spring pressedjpawl vpivoted thereon to rotate the shaft 63 by reason of the engagement between the said pawl and the ratchet (ist carried by the said shaft. The gear wheels 10ft being mounted upon the shaft 63, it is apparent that the entire-carriage is moved longitudinally with respect to its supporting structure. by reason of the engagement between thesaid gear wheels and the teeth of the rack bars2. To adjust the step by step movement v0f the carriage, the pawl 102 should be shifted upon the shaft 8.3 so as to engage any one of the several series of serrations formed upon the blocks 101, thereby limiting the 'rotary movement of the shaft 63 during the operation of the device.

Simultaneous with they step by step move- 4 `ment is imparted to the frame 112, this-being 4accomplishedby reason of the engagement between the pin 100 and the plate member 135 depending from the said frame. The cam 99 to which the pin 100 is secured being 'movable with the frame 77 and the shaft 85, it is vapparent that the frame 112 will be raised and lowered simultaneously with the oscillation 'of 'the frame 77. The movement of the frame 112 will raise and lower the circular file 120 respectively out of and into engagement with the teeth of the saw, and as the said file is driven from the shaft V108 through the chain of gears provided therefor, yit is apparent'that the teeth ofi the saw maybe 'filed or sharpened engagement with the sawactedupon during 'j the forwardmovement ofthe carriage, `and as the carriage moves sufiiciently to position the teeth thereof from'engagement by the anvils 44, it will bey observed that only every other tooth of'thefsaw is filed." j Angularadjustment of the circular file 12() maybe effected by adjusting theA plate member 132, the degree of adjustment being ascertainable by the relative position of the lip 133 With respect to the graduations or notches 114 of the head 113-of the frame. j Y

It being necessary that the paWl 102 should be removed from engagement With' the-serrations of the blocks 101 during the step by step movement of the carriage, means have been provided for actuating the said pawl, such means comprising the arm S1, one end of whichl is secured to the frame '77 and theopposite end to a link 84 in turn secured to the shaft S5 upon which the paWl is mounted for sliding movement. The

springS? serves asv a cushion to yieldably maintain the pin 83 of the said link in engagement With one end of the slot 82 of the said arm 81.

The carriage having been moved until all of the teeth ofthe saw have been set by the anvil blocks 44, andl every other tooth sharpened by the file 120, a second step by step operation of the carriage is necessary to provide for a sharpening or filing of the saw. During a second operation, the anvils 44 are rendered inoperative by adjusting the thumb nuts 23 upon the rods 26, thus permitting the file 120 to be raised and loweredy Y.

so as to engage every other tooth of the saW and thus sharpen the same in a manner similar to that above described.

By the manipulation of the thumb nut 7 9 it is apparent that the position of the bracket 6G may be varied, as the arms 68 and 73 connecting the said bracket 66 with the rocker frame 77 are so arranged as to be adjusted vertically with respect to the rocker frame. The manipulation of the thumb nut 95 Will, in a manner similar to that just described, vary the position of the bracket 94 and accordingly increase or diminish the pivotal movement of the cam 99.

Lateral adjustment of the sections of which the carriage is composed is eected through the operation of the thumb nuts 12 and gage screws 10.

It will be further seen that the machine is so timed that the movement of the carriage and the setting of the teeth follovi7 in exceedingly rapid succession, so that it requires only a minimum amount of time to properly set and sharpen the saw.

In reduction to practice, I have found that theformr of my invention, illustrated 'in the drawings and referred toein theabove description, as the preferred embodiment,' is

themo'st 'efficient and practical; yet realizing 1 thaty the conditions concurrent with `,the

adoption 'of my device ivill necessarily vary, v

I desirey to emphasize the fact that various minor" changes in details of construction,

proportion and arrangement of parts may Y bezresorted to, When required, Without sacricing any of the advantages of my ,inve-ntion, lasdeined inthe appended claims.
